ABSTRACT:
A brake lever connecting bar is formed from a tube, the ends of which become jaws by the insertion of a preformed insert that engages the parallel side walls of the tube increasing the wall thickness in which bearing surfaces are then cut. The remaining parallel tube walls are notched defining the reinforced jaw configuration required to connect brake levers on a typical railway car brake mechanism.
